362308, 362256, 362309, 362336, 362338, 362346, 362347, 257 98

Abstract:

An LED or incandescent light source is positioned in a reflector arranged to reflect light from the LED or incandescent light source which is radiated from the LED or incandescent light source in a peripheral forward solid angle as defined by the reflector. A lens is disposed longitudinally forward of the LED or incandescent light source for focusing light into a predetermined pattern which is radiated from the LED or incandescent light source in a central forward solid angle as defined by the lens. The apparatus comprised of the combination projects a beam of light comprised of the light radiated in the central forward solid angle and peripheral forward solid angles.

Illumination Management Solutions, Inc. - Irvine CA

International Classification:

F21V 7/20

US Classification:

362296, 362294, 362310, 362800

Abstract:

A module, or collection of discreet components, for an LED flashlight is coupled to a conventional flashlight body which includes a conventional power source. The module comprise a housing adapted to be coupled to the flashlight body; an LED light source coupled to the power source; a heat sink coupled to the housing, which heat sink is thermally and mechanically coupled to the LED light source; and a reflector coupled to the housing and having an optical axis. The LED light source is positioned by the heat sink on or near the optical axis and is optically coupled to the reflector. The reflector reflects light from the LED light source in a forward direction. The module, and/or components, is arranged and configured to be operatively coupled as a unit to the flashlight body and power source.

Assignee:

Illumination Management Solutions, Inc. - Irvine CA

International Classification:

F21V 9/00

US Classification:

362293, 235373

Abstract:

A plurality of light sources, each radiating a color of light; a corresponding plurality of reflectors are arranged and configured so that the reflector reflects light from a predetermined one of the plurality of light sources. The reflected light from the plurality of reflectors is mixed to generate a composite light from the plurality of light sources. A sequenced or stacked array of the light sources and dichroic reflectors mixes the reflected light from the reflectors. Each reflector is positioned on a common optical axis with an aligned corresponding one of the plurality of light sources to provide a light source and reflector pair. Each reflector is coated with a dichroic filter material which reflects the color of light radiated by the corresponding light source of the pair, and which transmits light radiated by all preceding light sources in the sequenced array.

International Classification:

F21V 7/00

US Classification:

362341, 362347, 362327, 362296, 313113, 359726

Abstract:

A reflector for a light source, such as an LED, is provided with a shape which efficiently collects and directs energy to an illumined surface whereby almost 100% of the light is collected and distributed into a designer composite beam. The shape in one embodiment is comprised of three zones beginning with a parabolic surface of revolution at the base of the reflector, followed by a transition or straight conic zone and ending with an elliptical zone. In another embodiment the reflector shape is determined according to a transfer function which allows for arbitrary designer control of the reflected rays at each point on the reflector, which when combined with direct radiation from the source, results in a designer controlled composite beam or illumination. The device is more than 90% energy efficient and allows replacement of higher power, less energy efficient light sources with no loss in illumination intensity.

International Classification:

F21V 7/00

US Classification:

362241, 362247, 362296, 362327

Abstract:

An LED having a predetermined direction of radiation is combined with a first and second reflector. The first reflector opposes the LED and has a predetermined direction of reflection. The direction of reflection of the first reflector opposes the direction of radiation of the LED. The second reflector has a predetermined azimuthal direction of reflection. The second reflector positioned relative to the first reflector to receive light from the first reflector and redirect the light into the azimuthal direction of reflection. The LED, first and second reflectors collectively comprise an illumination unit. A plurality of illumination units are axially stacked. In one embodiment of the stack, at least one illumination unit comprises an LED and second reflector of one illumination unit and a first reflector of an adjacent illumination unit in the stack of illumination units.

Abstract:

An apparatus includes: a plurality of light emitting diodes (LED) of similar or differing wavelengths; a reflector for collecting energy from two or more LEDs into an approximately composite beam; and a housing for distributing this energy into a common aperture. A heat sink and electronic control for the individual LEDs is included. The LEDs have different color outputs and are selectively controlled to determine the color of light from the apparatus. In one embodiment there are at least two LEDs, at least two reflector cavities, a common combining cavity or zone, a mounting each of the LEDs within the reflector cavities and a housing. The LEDs are mounted on the heat sink And selectively driven to modulate the intensity of selected ones of the LEDs according the nature of the frequency bands in the driving signal, e. g. mixed color outputs according to the control of a musical signal.
